To solve that, I used 'sudo dpkg --remove --force-all openjdk-9-*'. But, on the place of *, you put the rest of the name package. Example: sudo dpkg --remove --force-all openjdk-9-jre-headless
OR DO THIS, and MAYBE work sudo dpkg --remove --force-all openjdk-9-jre-headless sudo dpkg --remove --force-all openjdk-9-demo sudo dpkg --remove --force-all openjdk-9-dbg sudo dpkg --remove --force-all openjdk-9-doc sudo dpkg --remove --force-all openjdk-9-jre sudo dpkg --remove --force-all openjdk-9-jdk sudo dpkg --remove --force-all openjdk-9-jdk-headless sudo dpkg --remove --force-all openjdk-9-source Then: sudo apt-get install openjdk-8-* -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1551532 Title: java crashed with SIGABRT in JNU_GetEnv() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-9/+bug/1551532/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
